VAPORIZEB FOR INTERNAL-COMBUSTION ENGINES.

Application filed April 13, 1923. Serial No. 631,952.

To all whom it may concern:

Be it known that I, FIELmNo M. STAR-- BUCK, a citizen of the UnitedStates, residing at Summersville, in the county of Nicholas and State ofWest Virginia, have invented a new and useful Vaporizer for Internal-Combustion Engines, of which the following is a specification.

This invention relates to Vaporizers for use in connection with theintake manifold of an internal combustion engine.

The object of the invention is to provide a device extending through theintake manifold and connected with the exhaust to provide a heatedsurface for contact with the fuel entering the manifold from thecarbureter whereby the fuel is vaporized and rendered more readilycombustible.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made Within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawin s Figure 1 represents a side efiavation of aportion of an internal combustion engine showing the intake and exhaustmanifolds with this improved attachment ap lied, and

Fig. 2 is a front elevation of t e intake manifold showing it connectedwith the carbureter, arts being broken out and in sec tion to disclosethe attachment constituting this invention. v

In the embodiment illustrated, an intake manifold 1 is shown of usualconstruction 7 except that the upright leg or pipe thereof 15 made openat its lower end and closed by a nut 2, the'laterally extending tubulararm 3 being connected with the carbureter 5 as shown at 4. Extendingthrough the manifold 1 is a heating device in the form of a tubularmember 10 which projects at its opposite ends thro h the manifold, theupper end 11 thereof ing threaded for connection with a flexible pi e 12which unites it with the exhaust manifold 13 b a coupling 14 so thattheheated gases rom the exhaust will be fed throu h pipe 12 into pipe 10and pass out throng its open lower end to the atmosphere. This tube 10is here shown equipped with a fuel absorbing medium in the form of anasbestos fiber tubular wick 15 which will absorb the fuel admitted fromthe carbureter, permitting saturation of the wick by capillaryattraction. Around this wick 15 is arranged a resistance or heating coil16 disposed exteriorly of the tube 15 and having one terminal 17connected to and insulated from the manifold While the other terminal 18is connected to the tube 10. This wick 15 and resistance coil 16 aresimilar to those shown in my Patent No. 1,194,437, dated August 15,1916, and are designed to heat the fuel and vaporize it to facilitatestarting of the engine.

It will thus be seen that the tube 10 which is arranged longitudinallyin the path of the fuel passing from the carbureter to the cylinder willpresent a heating surface and t e entering fuel and cause it to vaporizeand pass into the cylinder in a readily com-- bustible condition, theheat being supplied,

to said tube 10 after the engine is started from the exhaust manifold inthe manner above set forth the electric heating coil which initiallyheats the fuel to facilitate starting being cut-ofl' by any suitablemeans, not shown.

Various changes in the f rm, shape, pro-v portion and other minordetails 'of construction may be made without departing from theprinciple or sacrificing any of the advantages of the claimed invention.

The combination of an intake manifold of an explosive engine, a pipeextending through said manifold and adapted to be connected to theexhaust of the engine, a fibrous fuel absorbing tube surrounding saidpipe within the manlfold, an electric resistance coil surrounding saidtube and connected to initially heat the fuel absorbed by thetube tofacilitate starting of the engine the pi e connected with the exhaustcontinuing t e vaporizing of the fuel after the electric heater has beencut-off.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
